FIG. 1 is a perspective view of a spool hub connector unit showing my new design;

FIG. 2 is an outside elevational view of the connector unit shown in FIG. 1;

FIG. 3 is an edge view thereof, it being understood that all edge views are round, and hence, are the same;

FIG. 5 is an enlarged perspective view taken from above and to the side of FIG. 2; and

FIG. 6 is an enlarged view taken from below and to the side of FIG. 4.

(1) The broken line showing of a ribbon feeding from between a vertical pair of disc sidewalls shown in FIG. 1 and in FIG. 3, and

(2) an abbreviated showing of a cylindrical spool area made clear in FIG. 3 is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a spool hub connector unit, as shown and described.
